SAW-SETTING MACHINE.

SPECIFICATION forming' part of Letters Patent NO. 764,858, dated July12, 1904.

Application filed January 18, 190% Serial NO. 189,594. lNO model.)

,TO [U '[flbmrb it Huby concern:

Be it known that I, JOHN S. MAsON, acitiZen of the United States ofAmerica, residing at Santa Ana, in the County of Orange and State ofCalifornia, have invented certain neW and useful Improvements in SaWSetting Machines. Rotary, Of which the following is a specification.

This invention relates to metal tools and implements, and particularlyto aclass thereunder lnoWn as saw-Setting rotary.

An Object of this invention is tO produce a saw-setting device Whichautomatically feeds the SaW or carries said saW to bring its teethsuccessively into engagement With the saW- setting means, Which isrotated in unison With the feeding mechanism.

Furthermore, an Object of the invention is to produce a saw-settingmachine in Which One of the saw-setting Wheels is positively driven andin the provision of means hereby the Companion member or Wheel isdriventhrough the medium of a certain gearing connected to thepOsitiVely-driven member.

Furthermore, an object of the invention is to provide a novel framecontaining bearings for the reception of the rotating parts of thedevice, the said frame having means for permitting the adjustment of themembers With relation to each other and means also for securing theframe in position for operation.

Further-more, an object of the invention is to produce a saw-settingmachine having a plurality of interchangeable parts, Whereby a rip-saw,band-saw, or Ordinary crosscutsaW may be acted upon and eifectually setby the same apparatus.

Finally, an object of the invention is to produce a saw-setting machineof the Character noted Which Will possess advantages in points ofsimplicity, efficiency, and durability, proving at the same timesatisfaetory in use and Comparatively inexpensive to manufacture.

Vith the foregoing and Other objects in view the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference Will be had to theaccompanying draW- ings, forming part of this specification, Whereinlike characters denote corresponding parts throughout the several vieWs,in which Figure 1 is a vieW in clevation ill'ustrating a saw-settingmachine embodying the invention. Fig. 2 illustrates fragments of thefeeding and setting Wheels detaehed. Fig.v 3 illustrates the undersurface of the feeding-Wheel. Fig. 4 illustrates the upper surface ofthe setting-Wheel. Fig. 5 is a detail vieW showing the adjuSting-block.

In the draWings, 1 denotes the frame, having a clamp member 2 With athreaded aperture for the reception of the thumb-scrcW 3, Whereby theframe is Secured to a bench or table 1 of any Ordinary construction. Theframe has tWO bosses 5 and 6, Which have vertically-disposed recessesforming bearings for the short shafts 7 and 8, respectively. The framehas a longitudinally -disposed ScreW- threaded aperture 9 for thereception of the thuInb-screW 10, the said thumb-screW 10 being sWiVeledin a bearing-block 11, Which bearing-block is slidable in the elongatedrecess Which is formed in the boss 6. The bearing-block 11 has ahalf-bearing in its inner surface Which bears against the Shaft 8, sothat the Shaft may be adjusted toWard Shaft 7.

An arm 12 has a right-angular extension provided With an elongatedopening 13 for the reception Of a bearing-block 1 1, similar to thebearing-block 11, heretofore described. A thumb-screW 15 is sWiveled inthe block 1 1 and is threaded in the ap'erture 16 of the arm 12.

The Shaft 8, as stated, is rotatable in the boss6 and in the extensionof the arm 12 and is designed to Carry one of the saW setting members17, Which saw-setting member has a recess 18 in its under Surface forthe reception Of a stud 19, Which projects from the upper Surface of thegear-Wheel 19. The

Saw-setting member 17 has a series Of radial slots 20 and ribs on itsupper surface, into Which a series of ribs 21 of one feeding member 22are Seated in order that the members 17 and 22 may be moved or rotatedtogether.

The gear-Wheel 19 is loose On the Shaft 8, V

and the members 17 and 22 may be connected members 26 are of slightlyless diameter than to the said gear-Wheel through the medium the settingmembers in order that the saw of the stud and the ribs just described,so that the said setting and feeding members may be readily removed byWithdraWing the Shaft from its bearings. Of course, if it is desired,all of the members on the Shaft may be keycd thereto; but it has beenfound in practice that the parts are more readily disconnected by havingthem joined in the manner stated.

It iS to be understood that the bearingbloeks 11 and 14 engage the Shaft8 and retain it in certain relation to the Shaft 7 in order that thecoperatingsetting members may be moved to accommodate saWs of differentthicknesses, and it Will lOe understood also that the Said members maybe removed for the purpose of substituting those having accommodationsfor teeth of larger or smaller siZes.

Coperating With the parts 17, 19, and 22 are a set of positively-drivenmembers consisting of a gear-Wheel 23, Which has a loWer beVel-gear 24,the Said gear-Wheel 28 having a stud connection With the setting member25 and the said setting member 25 having a slotand-rib connection Withthe feeding member 26, similar to that heretofore described.

The Shaft 7 has its upper end Inounted in a bearing formed on the arm27, Which arm at its loWer end is integral With the frame 1. Alntermediately of the arm 27 a bearing 28 is formed, in Which is mounteda short Shaft 29, the said short Shaft 29 being provided With acrank-handle 30, by which it is rotated. On the inner end of the Shaft29 is a pinion 31, meshing With the bevel-gear 24. Hence as thecrank-handle is rotated the pinion communicates motion to the gear-Wheel23 and to the Shaft 7, on Which the parts 25 and 26 are mounted in anysuitable manner.

The faces of the tWo coacting setting members are provided With recesses32 for the accommodation of the points of the teeth of the SaW, the saidrecesses being of such size as to receive the said teeth and the saidmembers being interchangeable for the purpose of substituting membershaving recesses of different sizes. It is observed that the feeding maybe fed between the rollers While the teeth thereof depend between thesetting- Wheels, the said Setting-Wheels having teeth which oppose therecesses of the coacting Setting-Wheel. The recesses 32 are formed inthose portions of the setting member between the radial slots 20.

Having fully described the invention, What I Claim as neW, and desire tosecure by Letters Patent, is-- v 1. In a saw-Setting machine, a suitableframe, shafts supported on the frame, intermeshing gear-Wheels on theshafts, and means for rotating the gear-Wheels, setting-Wheels on theshafts, connections between the gear- Wheels and setting-Wheels Wherebythe latter are rotated With the gear-Wheel, the Said setting-Wheelshaving peripheral teeth and Opposing recesses, for the reception of theteeth of the saW, the said setting-Wheels having radial grooves in theirupper faces, feeding- Wheels of less diameter than the setting- Wheels,having tongues fitting in the grooves of the setting-Wheels, and meansfor adjusting one Shaft toWard and away from the other Shaft.

2. In a saW- Setting machine, a suitable frame, shafts carried by theframe, intermeshing gear-Wheels On the Shaft means for rotating thegear-wheels, independent setting and feeding Wheels On the shafts,connections between the gear-Wheels and setting- Wheels, connectionsbetween the setting- Wheels and feeding-Wheels of each Set,Whereby thesetting and feeding Wheels are rotated With the gear-Wheels, the Saidfeeding-Wheels being of less diameter than the setting-Wheels, the saidsetting-Wheels having peripheral teeth and opposing recessessubstantially as described. A

In testimony Whereof 1 affix my Signature, in the presence of tWoWitneSses, this 7th day of January, 1904.
